Cecal diverticulitis: evaluation with CT.

The findings of computed tomographic (CT) examinations in seven patients with cecal diverticulitis are described and correlated with those of barium studies. The CT findings were linear and streaky densities in the pericecal fat compatible with pericecal inflammation (seven cases), intramural abscess (one case), thickening of the cecal wall (two cases), and cecal diverticulum (one case). Barium studies, available in four patients, led to a correct diagnoses of diverticulitis in two cases. CT scanning is a sensitive means by which to detect cecal diverticulitis. The radiographic appearance of the disease, however, mimics that of appendicitis, unless more specific findings such as cecal diverticula or intramural abscess with adjacent inflammation is detected. CT and barium study are complementary methods of examination that improve our ability to diagnose cecal diverticulitis and its complications.
